Description

The invention relates to a hose wire clamp arrangement according to the preamble of claim 1.

Hose wire clamps are known, which have the features of Have the preamble of claim 1, for example Connection of hoses in household machines and / or to Household machines in a relatively low pressure range up to typically 8 bar. Such a hose wire clamp has if it is not pinched open a slightly smaller one Diameter as the outside diameter of the hose for example, they should clamp on a connecting nipple. To assemble the hose, the wire connector is first pushed onto the hose, the hose on the Connection nipple is set. Around the hose on the connection nipple to clamp, the angled sections the tube wire clamp compressed, causing the hose wire clamp opens, i.e. their clear diameter is enlarged. So it can be on the hose in the Position the area of the connection means. In the right one Position are the angled sections of the hose wire clamp released, causing them to contract and firmly holds the hose on the connection nipple. - A disadvantage of this hose wire clamp is that at higher pressure, for example greater than 8 bar, the Hose wire clamp counteracted by the pressure in the hose the spring action of the helically bent wire can be expanded, causing the connection point to leak and the hose will even detach from the connection nipple can.

These disadvantages become form-fitting in another Avoid type of hose wire clamps when using eyelets with a Crimping pliers are pressed together. This during assembly irreversibly deformed hose clamp can be used in service can no longer be solved; that's why it's for example required to cut them open and replace them with a new one Replace hose wire clamp. Apart from that with it associated material requirements is disadvantageous that for assembly the hose clamp with a pair of pliers a big one free handling area is required.

The invention has for its object a hose wire clamp to create the type mentioned above, which itself for the non-positive connection of a hose on a Connection nipple is suitable and easy, even without tools is mountable, but also detachable and reusable and which is suitable for a high pressure in the hose or the connection nipple without leaking and loosening the hose to withstand reliably.

This task is accomplished through a hose wire clamp assembly solved with the features of claim 1, to the essential Element belongs to a locking plate. This has two cutouts arranged at a distance from one another, on which one of the two angled sections of each Hose wire clamp in the assembled state of the hose wire clamp arrangement is present. With the locking plate is achieved that even at higher pressure in the hose helically curved spring wire not automatically can expand undesirably because its both angled Sections are prevented by the locking plate to move towards each other. However, if desired is to disconnect the hose connection first the locking plate from the angled sections of the helically bent resilient wire removed be what these angled sections look like allow to squeeze manually. Except for the application the locking plate and its removal from the Tubular wire clamp is therefore handled conventionally.

So that the locking plate fulfill the locking function and the hose wire clamp even at relatively high pressure in a safe, maintains a positive connection with the hose, is to dimension the locking plate according to claim 2 so that the distance between facing edges of the two Cutouts of the locking plate is at least as large as the distance between the two angled sections of the hose wire clamp in a relaxed state.

With the width of the locking plate perpendicular to the above Distance can be the correct positioning of the Hose wire clamp specified on the connection nipple and be easily controlled.

According to claim 3 suitably belongs to the hose clamp assembly a hose wire clamp that from the first angled section over a first helical Section, an angled and partially bent back, approximately U-shaped connecting section as the second bent section and a second helical Section to a third angled section runs, the first angled section and the third angled section lie close together and being between two legs of the second angled section the two helical sections of the resilient wire. Belongs to this hose clamp particularly advantageous a locking plate, which is the first Cutout an open cutout at an end section has and at a distance from this a hole as a second cutout in a closed section of the locking plate having. The locking plate can then be simple and reliable in the way that is positioned on the hose and applied the hose-clamping hose wire clamp be that the locking plate with its open Detail of the first angled section and the third angled section of the tubular wire clamp is pried and then on the angled and partially bent back, pivoted approximately U-shaped connecting portion being, this second angled section into the hole of the locking plate snaps into place. After that lie the first angled section and the third angled section the hose wire clamp on the first open section of the Tab washer and the second angled section in the Hole as the second cutout of the locking plate, so that this is captively pinched.

An embodiment of the invention is explained below with reference to a drawing with a figure, from which further features, in particular with regard to the shape of the hose wire clamp and the locking plate, their interaction and the advantages achieved therewith emerge. It shows:

Fig. 1

a hose wire clamp with a releasably connected locking plate in a diagrammatic view.

In Fig. 1, 1 generally denotes a hose wire clamp and with 2 a locking plate detachably attached to it.

The hose wire clamp 1 comprises one at one end first angled section 3 and at its other end a so-called third angled close to it Section 4. Starting from the first angled section 3 follows a first helical section 5, which merges into a connecting section 6, which one so-called second angled section forms. Analogous for this purpose runs in from the third bent section 4 second helical section 7 to the common Connection section 6. The hose wire clamp 1 is overall bent so that the two helical Sections 5 and 7 in the area of the connecting section 6 of these are included. The connecting section In detail, as can be seen in FIG. 1, 6 is approximately U-shaped Shaped closed, so that an outer part to the first angled section 3 and the third angled one Section 4 is bent back.

The locking plate 4 is - before it bends - essentially rectangular. From it is a first on one edge, open cutout 8 formed and at a distance from this in an approximate closed section not designated rectangular hole 9. An edge 10 of the first section 8 is closest to one only indicated in FIG. 1 Edge 11 of the rectangular hole 9 adjacent. Parallel to and near the edge 11 is the locking plate 2 by one obtuse angle bent. This curved shape has under another advantage that they approximate the shape of the Adjusted hose wire clamp and thus a compact unit results.

The tubular wire clamp 1 is first on a not shown Hose that is on a likewise not shown Connection nipple is to be clamped, applied by the first bent section 3 and the third angled Section 4 on the one hand and the second bent section 6 on the other hand compressed in the direction of arrows 12, 13 be, whereby the inner diameter of the helical Sections expanded and the hose wire clamp can be positioned at the desired location. This Positioning can be checked with the locking plate 2 which with its edge 10 at the bottom of the first angled section 3 and the third angled section 4 is created. Then it will Locking plate 2 in Fig. 1 to the right on the second angled Section 6 pressed so that this in the hole 9 slides until the connecting section 6 in the in Fig. 1st shown position rests on the edge 11 of the hole 9.

Due to the distance between the two edges 10 and 11 the distance between the first angled section 3 and the third angled section 4 on the one hand and the second angled section, i.e. Connecting section 6, on the other hand, be larger than in the state of the tubular wire clamp 1, in which this the hose on the connection nipple without locking plate. The locking plate thus results 2 an increase in the adhesion of the hose wire clamp 1.

The locking plate can easily be removed from the hose wire clamp be solved by the locking plate in Fig. 1 to the left is pivoted back, the connecting section 6 slipping out. Then the locking plate from the angled sections 3 and 4 are removed and the Hose wire clamp can be squeezed in the direction arrows 12, 13 can be released.
